Another piece in the puzzle
Pulmonary ischemia-reperfusion injury is complex and involves many cell types and mechanisms of action. Van Putte and coworkers have attempted to provide insight into and describe some of the complex components of this process. Their study describes two new components of the multifaceted process of reperfusion injury. The time-dependent course of neutrophil activation and the discovery of progr...
متن کاملAnother piece of the meiosis puzzle
M the process by which the ovary and testis produce haploid gametes from initially diploid cells, is essential for sexual reproduction in mammals. This process, initially described in the late 19th and early 20th century using model organisms such as sea urchins, worms and fruit flies, continues to attract extensive interest from reproductive biologists due to its centrality in gametogenesis. T...
متن کاملAnother Piece of the p27Kip1 Puzzle
How extracellular signals communicate with the cell cycle is poorly understood. In this issue, two papers address this problem by reporting phosphorylation of the cyclin-dependent kinase inhibitor p27Kip1 on a tyrosine residue by nonreceptor tyrosine kinases, which decreases p27 stability. This new mechanism could explain how cells enter the cell cycle from a quiescent state.
متن کاملHypercapnia From Hyperoxia in COPD: Another Piece of the Puzzle or Another Puzzle Entirely?
Embarrassment is a powerful teacher. I was barely 3 months into my internship, on night float at my residency’s Veterans Affairs hospital, when I received a page from a concerned ward nurse. A patient was unresponsive. He was admitted for a severe COPD exacerbation. I examined him, and he only groaned with a vigorous sternal rub. Suspecting hypercapnic narcosis, I drew an arterial blood gas. Th...
متن کاملFGF23 and vascular calcifications: another piece of the puzzle?
At the time of its early discovery and characterization, fibroblast growth factor 23 (FGF23) was identified as a hormonal substance produced by bone cells (osteoblast/osteocytes)mainly devoted to controlling phosphorus balance by directly reducing phosphate reabsorption in the proximal renal tubule and indirectly decreasing phosphorus intestinal absorption, through a reduced bioavailability of ...
